Check whether disabling extensions and then clearing the browsing data will have a positive impact.

If you don’t want to Download the app they suggested, I suggest you to install BitDefender since its more well known software and its shown that it detects that virus.
And I too would suggest you to use BitDefender instead of any other Antivirus since it works the best even if you just use the Free Version…
If you haven’t set your Brave Shields to aggressive before clearing Site and Shields Settings, I highly recommend doing so now. The exceptional work of @fanboynz and other Brave developers can save you from such headaches in the future.
I have never used MacOS but it looks like that crap is nothing new, you can also take a look at the thread below. You can find many threads where users are given instructions, might take you some time.
Well I cleaned my mac and so and there’s nothing wrong (according to three different antivirus)
BUT I Found the Solution
So for anyone who has such problem even using every solution possible, including the malwarebyte solution here is how to perforn:
Create a new session like test sessions
Go to preference and copy the link of the preferred search engine (I personally use DuckDuckgo but you can take whichever is in the list like google for instance)
Go back to your main session and paste the link you just copied in the search engine section (in preferences)
Delete all others and select the new one you just copied as preferred search engine
Enjoy
Making regular check and cleaning of your pc/mac is always good
